Corrosion may develop at the connection between the ignition coil tower and spark plug wire resulting in an engine misfire. The Ignition coil and spark plug wire should both be replaced to correct this condition.

car was misfiring and had no power on acceleration. removed spark plug wires and found corrosion at coil plug. replaced all wires with new. also changed all plugs - one plug had cracked insulator and fell apart during removal.

I just replaced all my sparkplugs, spark plug housing, ignition coils, and sparkplug boots. (I was getting a missfire on cylinder 1 and a service vehicle soon light was flashing) Works great now!! Shops were quoting me 500-900 bucks to do this and I bought all the supplies and did it for less than 200. :)
